What is a water heater and what does it do?

Homeowners rely on their plumbing system and hot water heater to supply them with hot water for bathing, cooking, washing dishes, and doing laundry. While most conventional water heaters store water in a tank, there are also tankless water heaters, which heat water on demand. 

Water heater units are typically powered by electricity, natural gas, or propane. The first step in selecting a new water heater is to decide which fuel source will be used. Electrical power is the most common fuel source for home water heaters, but it is also the most expensive. Propane and natural gas tend to be less expensive alternatives, but they require special venting that may not be available in all homes. 

The next step is to determine the capacity of the new unit. A water heater unit’s capacity is measured in gallons, and home water heaters range in size from 20 to 80 gallons. For families of four or more, a 50-gallon or larger unit is recommended.

Homeowners should also consider the warranty when selecting a new water heater. Warranties typically cover the tank and parts for three to twelve years. Tankless water heaters often have longer warranties than traditional units. Finally, homeowners should have their new unit installed by a licensed professional to ensure optimal performance and safety. 

Signs you may have a leaky water heater

Homeowners usually don’t think about their water heater until it stops working. However, there are some obvious signs that a water heater may be in need of repair or replacement before it fails completely.
